The Rivet Nut is a one-piece internally threaded and counterbored tubular aluminum rivet that can be pulled up or headed while working entirely from one side, forming a bulge or head on the blind side. This upset is large enough to resist being pulled through metal or plastic even under conditions of eccentric load. It overcomes the difficulty of installing brackets, handles or other attachments to tubular pieces.

These little rivnuts make a great way to put threads in a hole. If youve got a #8 or #10 hole where a metal screw use to fit, but the hole has widened. Install these rivnuts and use a machined screw. Note you need a tool or bolt with nuts to install these. I used Keyless and worked fine.
